Casting Of New Technology Trends

China¡¯s accession to WTO and the world enters the 21st century, people from a different perspective, the development of casting technology, and published a number of writings, in order to provide people with a cast on the technological development of China¡¯s status and development trend of the overall concept, lead to more in-depth thinking colleagues , the writer¡¯s own understanding and making reference to a number of published literature, while absorbing some of the views of experts and scholars to form this article for peer reference.
The face of global, information, technology, rapid development of equipment manufacturing industry, machinery manufacturing industry in particular, the modernization level of high-speed increase, China (mainland where they talk about the situation, not including Taiwan and Hong Kong and Macao regions) foundry industry as a clear understanding of their own historical mission and the reality of the gap with the developed countries, bold use of modern science and technology, and management of the latest achievements and recognize "only to achieve high-tech technology to keep pace with the times", the grasp the development trend of modern casting technology, using advanced and applicable technologies, the implementation of sustainable development strategy, based on reality and the vision to revitalize and develop China¡¯s foundry industry for numerous achievements of China¡¯s modern industrial civilization has laid a solid foundation for the process.
Developed countries, Development of Casting Technology
Advanced casting technology in developed countries in general, product quality, production efficiency, less environmental pollution, raw and auxiliary materials, the supply has become commercialized series, such as in Europe, has established cross-border service system. Production of the universal realization of mechanization, automation, intelligent (computer-controlled robot operation).
Cast Iron smelting using large, efficient, dust, computer monitoring and control, external hot-air supply continuous operation without water-cooled cupola furnace lining, the widespread use of Foundry Coke, with cupola cupola or electric smelting furnace duplex, using a continuous nitrogen gas desulfurization or desulfurization of iron roll pack Liquid sulfur content up to 0.01%, the following: melting alloy steel refining multi-purpose AOD, VOD and other equipment, so that liquid steel in H, O, N to reach several or dozens of 10 ~ 6 level.
Casting in the important production, high requirements for materials, such as ductile cast iron requirement P less than 0.04%, S less than 0.02%, steel demand P, S were less than 0.025%, using timely and accurate control of thermal analysis technique C, S content of using direct-reading spectrometer 2 ~ 3 min analyze the element content and more than a dozen high accuracy, C, S analysis and control will enable ultra-low carbon stainless steel, C, S content can be accurately controlled, the use of advanced non-destructive testing technology to effectively control Castings quality. Commonly used liquid metal filtration technology, filters can be adapted to high temperatures, such as cobalt-based, nickel-based alloy and stainless steel liquid filters. After filtration of steel castings A-ray flaw detection passing rate increase of 13 percentage points, aluminum-magnesium alloy through a filter, casting tensile strength increased by 50%, elongation rate above 100%.
Widely used alloy cored wire processing technology, so that ductile iron, vermicular cast iron craft iron and nurture a stable, high rate of alloying elements collected, pollution-free process to achieve automatic control of the microcomputer.
Aluminum matrix composites can be extensive attention for its advantages and are increasingly turning to industrial-scale applications such as automotive drive rod, cylinder block, cylinder liner, piston, connecting rod and other parts are available in a variety of important production of aluminum matrix composites, and has been at the senior Racing on the application; in the car to the lightweight development process, using a variety of important production of magnesium alloy auto parts has been second only to the amount of aluminum alloy.
Using hot air cupola, the two rows of large spacing and oxygen blast cupola, electric furnace with furnace charge preheating, lower melting temperature, increase the operating rate of the stove to reduce the lid open time, strengthening and implementation of computer-controlled optimization of thermal melting process. Ductile Iron Castings Production in the widespread adoption of small riser and non-riser casting. Cast Steel riser with insulation, thermal insulation subsidies, craft production rate from 60% to 80%. Consider the labor costs are high and production conditions in poor factors, large-scale use robots. The strict rule of law because of environmental considerations (EAF dust has nine States under 100 ~ 250 mg/m3, the sky grate dust, 11 countries provided 100 ~ 1000 mg/m3, or 0.25 ~ 1.5kg / t liquid iron; sand dust, 8 States under 100 ~ 250 mg/m3), casting plant all attach importance to environmental protection technology.
In the high-volume production of small castings, they use a computer-controlled high-density static pressure, shooting pressure or air impact modeling mechanization, automation and efficient assembly line green sand molding process, high-efficiency continuous sand sand machine, artificial intelligence, sand control experts online systems, core technology commonly used resin sand hot, warm and cold-box method-box method. Casting generally done using silica sol and ethyl silicate binder system, shell craft.
Production of aluminum die-casting machine with automatic cylinder body, cylinder head; has built a number of iron-based alloy low pressure casting production line. With the differential production of special steel casting foundry. Produced by centrifugal ductile iron pipe of various calibres, accounting for more than 95% of the total cast iron pipe, ductile iron pipes ductile iron output accounted for 30% ~ 50%.
The successful adoption of EPC technology, mass-produced automobile cylinder body, cylinder head castings and other complex, productivity up to 180 / h. In the process design, mold processing, the use of CAD / CAM / RPM technology; specialized in casting machinery, complete sets of preparation, have started using CIMS technology.
Casting the whole process of the initiative, and strict implementation of technical standards, casting reject rate of only 2% to 5%; standard update fast (standard age of 4 ~ 5 years); generally hold ISO 9000, IS014000 certification.
